What is an appropriate antonym for deficient?

The dissertation is deficient of sources.

It should be a bit more decorated than the phrasing The dissertation contains enough sources.

The phrasing is deficient of, is at the very least, unusual phrasing. Letting that pass, the "antonym" would actually have to mean "has too many sources". But I imagine all you really want to say is something in the range "is adequately sourced" through "is well-sourced" to "is exhaustively sourced" – FumbleFingers Jan 31 '12 at 23:26
@FumbleFingers Thumbs up. Your comment is very helpful to me. – Em1 Feb 1 '12 at 8:10

You could say it is replete with sources:

replete adjective [ predic. ]
filled or well-supplied with something: sensational popular fiction, replete with adultery and sudden death.

Sufficient, without doubt!

  1. Equal to the end proposed; adequate to wants; enough; ample; competent; as,
  2. Possessing adequate talents or accomplishments; of competent power or ability; qualified; fit.

Hmm. "The dissertation is sufficient of sources" doesn't really do it for me. – FumbleFingers Feb 1 '12 at 2:19

The dissertation has a surfeit of sources.

The dissertation is over-endowed with sources.

But only if you consider a surplus to be the opposite of a shortage.

Yes, I didn't want to say that there are too much sources. It wasn't clear to me, that this were the exact opposite of deficient. But I like your examples. – Em1 Feb 1 '12 at 8:15

The dissertation is a cornucopia of resources.

Replete came to my mind as well. Abundant is the opposite of deficient.

Edit to add explanation:

Both the answer choices replete and abundant are synonymous. Replete has already been explained by Robusto who posted the answer choice first.

Deficient means lacking in something. The opposite would be having it in excess. Therefore, abundant is the opposite of deficient.
